The widow of a Dallas firefighter killed in the line of duty last year is demanding answers from the city about her husband’s death.

Jenny Wilson said Wednesday she has been waiting patiently for 14 months and wants to know what caused the death of her husband of more than 20 years, Stanley Wilson, on May 20, 2013. Wilson’s longtime friend, retired firefighter Jim Crump, has publicly said he believes commanders are covering for a deputy chief who allegedly sent Wilson and others back into a collapsing building long after it was safe to do so. The deputy chief still works for Dallas Fire-Rescue.

Wilson, now a single mother of two teenage boys, had Arlington lawyer Barry Hasten send a letter last week to Chief Louie Bright III requesting the line-of-duty death report or a date when the investigation would be released.

“I don’t understand why the report is being held because I think it’s complete,” Wilson said. “They’re not doing right by him. They’re not doing right by me and my boys.

“Out of respect for Stan, I would hope the fire department would no longer hesitate in releasing the report or at least privately providing my family answers.”

Hasten, who said he has handled fire investigations for clients for years, echoed those sentiments in his letter to Bright.

“Due to the fact that most, if not all, witnesses are under your control, it’s difficult to understand why the investigation has taken this long,” Hasten wrote.

Hasten says in the letter that he was retained for now only to get a copy of the investigation.

Dallas Fire-Rescue Lt. Joel Lavender, a spokesman for the department, said Wednesday that he is “anxiously awaiting” the completion of the report. But he declined to comment further, saying the investigation was still underway.

He has previously said that line-of-duty death reports typically take eight months to a year and that the department wants to get the investigation right.

The State Fire Marshal’s Office and other agencies are also investigating Wilson’s death.

Wilson was crushed to death by a collapsing building in the six-alarm blaze in an apartment complex in the 12300 block of Abrams Road. Crump said Wilson would not have gone back inside the building without an order.

“When Chief Bright spoke at Stan’s funeral, he said Stan never hesitated when he went into that building,” Jenny Wilson said. “I don’t think in 28 years Stan ever hesitated when given an order.”

In the initial months after her husband’s death, Jenny Wilson did not publicly question the actions taken the night of the fire.

But around the first anniversary, she said she was struggling to cope with his absence. She also found it “almost incomprehensible” that the report wasn’t out yet. She said her husband would be demanding answers, too, had someone else been killed.
